First do it,then do it right,then do it better.

Why work at Ahrefs

We are a small team that strongly believes that better technology leads to better solutions for real-world problems. We worship functional languages and static typing, extensively employ code generation and meta-programming, value code clarity and predictability, and constantly seek to automate repetitive tasks and eliminate boilerplate. We are guided by DRY and follow KISS. If there is new technology that will make our life easier, we'll give it a try. We rely heavily on open-source code (as the only viable way to build maintainable system) and contribute back, see e.g.
